摘要/Abstract

摘要： 文中引入软件定义网络(Software Defined Network,SDN)对智慧医疗云进行网络管理,并且针对传统SDN控制器存在单点失效和负载均衡的问题,设计了智慧医疗分布式SDN控制器系统。SDN控制系统分为SDN控制器集群、数据转发平面和智慧医疗云服务系统3层。在此基础上,提出一种实时负载动态自调节的快速负载均衡算法DAF(Dynamic Adaptive and Fast Load Balancing)。在该算法中,负载信息感知组件周期性地采集自己的负载信息,自动地进行控制器间的负载信息交互;控制器的负载值超过阈值时,会触发交换机迁移动作,以动态配置交换机与控制器之间的映射关系。实验结果表明,面向智慧医疗云的分布式SDN控制系统的性能良好,且DAF算法能够快速地实现SDN控制器间的负载均衡,提升了智慧医疗云的网络吞吐量。

Abstract: This paper introduced software defined network (SDN)to manage smart healthcare cloud network,and designed a smart healthcare distributed SDN controller system to address the problems of single point failure and unba-lanced load distribution in traditional SDN controller.This system is composed of three layers:SDN controller cluster,data forwarding plane and smart healthcare cloud service system.On this basis,this paper proposed a DAF (Dynamic Adaptive and Fast Load Balancing) algorithm.In this algorithm,the load information aware component periodically collects its own load information,and automatically interacts the load information between controllers.When the load value of controller exceeds its threshold,the switch migration action is triggered to configure the mapping relationship between switches and controllers dynamically.The experimental results show that the distributed SDN control system for smart healthcare cloud has good performance,besides,the DAF algorithm can quickly balance the load among the SDN controllers and improve the network throughput of healthcare cloud.

Key words: Controller cluster, Load balancing, Single point failure, Smart healthcare cloud, Software defined network
